Out of curiosity, what problem are you solving for using small calibers on large game? Is this for a small framed shooter or something else? I ask as I personally would not consider this proper, common practice or recommended by those with elk experience.
Honest question. Not trolling you.
Thanks
At a minimum, go to page one, look for the cheat sheet, and see the results.
And most, buy a tikka in 223, shoot some high quality projectiles with a reliable and well mounted scope at a few critters and see the results yourself.
But in all seriousness, cheap to shoot and light recoiling rifles mean you will shoot more. You shoot more you get better. You get better, you put more well placed shots on animals. Well placed shots on animals make em die. More animals die with less fuss, you have more fun hunting.
Your success rate goes up, you shoot more, and you can teach new shooters or kids on your super gentle and cheap to shoot gun.
Aside from all of that, there is some terminal ballistics to study, and if you read the thread you’ll probably be surprised at how impressive the 223 caliber can be on big game, and you will probably have a lot of long held beliefs that will be challenged. Just approach with an open mind, and a fresh cup of coffee for a few weeks, and you will probably be a believer.
At the end of the day, a good bullet will never overcome lack of training or unreliable equipment, so make sure you take a look at some of the training threads, scope mounting, and drop test threads.
